Brief introduction of lithium battery recycling technology

1. Pyrometallurgical method: use high-temperature roasting of discarded lithium batteries that have undergone simple mechanical rupture, and sieving to obtain fine powders containing metals and metal oxides. Characteristics of pyrometallurgical process: The process is relatively simple and suitable for large-scale solutions; the combustion of battery electrolyte and other components can easily cause air pollution. 2. Hydrometallurgy: After the waste battery is ruptured, it is selectively dissolved with a suitable chemical reagent to separate the metal elements in the leachate. Characteristics of hydrometallurgical process: Is the process stable enough for the recovery of small and medium-sized waste lithium batteries; the cost is high, and the waste liquid needs to be further solved. 3. Physical dismantling: The battery pack is broken, sieved, separated by magnetic separation, finely pulverized and classified to obtain high-content substances, and then proceed to the next step of recycling. The characteristics of the physical dismantling process: low solving efficiency and low time-consuming; the process is very environmentally friendly and will not cause secondary pollution to the environment. In general, waste lithium batteries are harmful to the environment, but their recycling value is high. Most of the metal elements contained in them are metal resources that are relatively scarce in my country, and imports rely on high levels of metal resources. At the same time, as far as the company is concerned, the recycling of used lithium batteries also contains business opportunities. After effective recycling solutions, it can save a large amount of processing costs for battery processors and has very high economic value.
